MIAMI (CBSMiami) – The Miami Dolphins are expected to run a hybrid 3-4/4-3 defense in 2012 and that means the team will need some depth at the linebacker position.

That’s why on Monday, the team brought in a familiar face to Florida State Seminoles fans for a workout. Former top 10 pick Ernie Sims, Jr. was worked out by the Dolphins along with fellow free agent linebacker Omar Gaither.

Sims was a standout linebacker at Florida State who ended up being overdrafted by former Detroit Lions general manager Matt Millen. Sims, 27, has freakish athletic ability, but has never been able to translate all of the skills onto the field.

Sims has also battled problems with concussions during his time in Detroit.

If the Dolphins are ready to move full-time to a 4-3 defense, Sims could be a candidate to start if the team wants to keep Koa Misi on the bench. Currently, the Fins have Karlos Dansby, Kevin Burnett, and Misi penciled in as starters.

Misi has been a disappointment since being drafted in the second round. He flashed moments as a rookie, but was never able to put it altogether as an outside linebacker in a 3-4 defense.

The Fins have previously added Gary Guyton to the linebacking corps who could slide in and be a starter if the team utilizes more of a 3-4 look.
